Patented Feb. 25, 1930 Y UNITEDTSTATES 1 FREDERICK A. KArrELMAnn, Di s-sm t; NEW YORK V coMrosnrIoN-rtoon s rmr H This invention relates broadly to protecting strips for composition floors.

One of the objects of this invention is to provide a strip adapted to be mounted be- 5 tween the adjoining faces of thesecti'ons comprising a composition flooring, such as concrete, terrazzo, and, in fact, a floor made of any of the usual floor compositions.

Another object of this inventlon 1s to pro- 10 vide a strip of this nature characterized-by the fact that it is securely attached to one sec-' flooring which is adapted to be embedded betweenthe sections which comprise the fiooring in such a manner that it is rigidly secured to the flooring on one side of thestrip and permitted guided movement with respect to the flooring on the other side thereof. 7 I

These and many other objects are success fully sought by means of thisinvention.

This invention resides-substantially in the construction, combination, arrangement and i 1' relative location of the parts as will appear from the following-description. I

lt-is nowcommon practice in the construction of modernfoffice and residential buildings, to provide aflooring composed of vari-, ous composition,materialbrokennp into a series of'squares or blocks and arranged to permitorelative movement between thevarious blockswtoaccommodatethefloor to changes in' temperature. i 'It has been common to place between the adjoining edges of the blocks comprising the floor protecting strips which willypermit relative movement of the various blocks' with respect;toeach'other, also prevent chippingxofthe blocks at, the edges and cracking thereof,- The typesof.. str1ps ordinarily-usedat the present time either move away'fromthe; edges of the; blocks so as to prevent protection thereof, or become bent v and 'di storted due totemperature changes a a protecting; stri-pq which v always remains o 1 7 straight and 'which -while per mitt ing rela theedges'thereof and, at the same time, "main:

the -stri'p,vwhil e thetabs 3 all project from the opposite side of the strip, ;g'l hem einbers or tabs 2 consistfof -plane members with a curved edge as shown in Figure2. The'propjecting imembersor abs l the s e 99 outline, are cupped or dished as at 4c. In Figures 5 and 6 the strip is shown at 5 having the tabs 6 which correspond to the tabs 3 of the other form of the invention, but in this case the tabs 6 are provided with a series of holes 7. In Figures 7 and 8 the strip is shown at 8 having the plane up struck tabs 9 all projecting from the same side of the strip and alternating with the tabs 10 which are struck up from the opposite side of the strip. The tabs 10 are split at their ends to provide the short arms 11 projecting at right anglesto the arm 10 as is shown in these figures.

In each of these forms of the invention a series of plane tabs as at 2 and 9 project from one side of the strip and alternate with a series of tabs projecting from the other side of the strip which may have a variety of forms of which three have been indicated in the. present drawings. It is, of course, evident that many changes in the details of construction and relative arrangement of parts will readily occur to those skilled in the art and I do not, therefore, desire to be limited to the particular form or relative arrangement of tabs or securing members on the strips.

I have shown in Figure 9 the way the strip co-operates with the various flooring sections. At 5 are shown two adjoining blocks between which is mounted the strip indicated at 1. The face of the strip having the cupped tabs 3 is rigidly secured against the edge of the lower block 5 by reason of the fact that the bination with a composition flooring having a' plurality of sections, of a protecting strip between-the adjoining faces of adjacent sections and cupped means on one side of said strip for securing it to one of said faces and additional flat means on the other side of said strip for at the same time permitting relative guided movement of said strip with respect to the other face.

In testimony whereof I have hereunto set my hand on this 1st day of March, A. D. 1927.

composition is packed around the cupped tabs to firmly embed them therein. When the form of strip shown in Figure 6 is used the tabs 6 having the holes 7 therein are firmly embedded in the flooring by reason of these holes. In the form shown in Figures 7 and 8 the projecting arms are firmly embeddedin the composition flooring by reason of the bent arms 11. The tabs 2, while they are embedded in the upper block, may readily move transversely with respect thereto when any relative movement between the blocks occur. In view of the shape of the tabs 2 it is evident that they are not firmly secured in the flooring composition and will readily move with respect to the block and be guided 7 thereby. V

It will be apparent from the foregoing descript-ion that a strip constructed in accordance with'the principles of my invention will always remain straight while protecting theedges of the blocks forming the floor as they move with respect to each other due to heat changes. V

. I"am,of:course, aware thatmany changes 1n the details of construction will occur to those skilled in the art and I do not, therefore, desire to be limited except as required by the appended claim. V
